Description of change

This change updates connection.parse_url to set ssl_cert_reqs=None for rediss:// connections.

$ rq info -u rediss://:**********@ec2-34-206-168-30.compute-1.amazonaws.com:29259
Error 1 connecting to ec2-34-206-168-30.compute-1.amazonaws.com:29259. [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1091).

I came across this error after migrating to a redis environment with SSL/TSL. I found that it was caused by the connection. Heroku's documentation recommends instantiating the redis connection with ssl_cert_reqs=None.

ssl_cert_reqs is not supposed to be None by default. See #1016
